Show answer & explanation
Correct answer: D
The correct matching is as follows:
A (Disk scheduling) matches with 2 (SCAN). Disk scheduling algorithms like SCAN are used to manage disk arm movement efficiently.
B (Batch processing) matches with 4 (FIFO). Batch jobs are typically processed in the order they arrive using First-In-First-Out queues.
C (Time sharing) matches with 1 (Round Robin). Time-sharing systems use Round Robin scheduling to allocate CPU time slices fairly among multiple users.
D (Interrupt processing) matches with 3 (LIFO). Interrupts are handled using a stack mechanism, where the last interrupt received is processed first (Last-In-First-Out).
Therefore, the correct code corresponds to Option 4.
